The VWCM-4000 Vibrating Wire Crack Meter is a precise structural instrument designed to monitor crack movement in concrete, rock and masonry structures. It measures changes in crack width with high accuracy, making it ideal for structural health and stability monitoring in bridges, dams, retaining walls and buildings.
Using vibrating wire technology, it converts displacement into a frequency signal, a signal that transfers reliable data with minimal degradation over time. The stainless steel construction provides durability in harsh environmental conditions, including exposure to water, temperature fluctuations and corrosive elements.
The VWCM-4000’s sensor is capable of detecting even the smallest movements, allowing engineers to assess crack behaviour and identify potential structural issues before they escalate. It is available in various gauge lengths and can be installed across surface cracks or embedded in joints.
Compatible with automated data logging systems, the VWCM-4000 supports real-time monitoring and remote access to data. Its low-maintenance design allows long-term deployment, making it a cost-effective solution for projects requiring continuous crack movement assessment and structural integrity monitoring.

The W1 Standpipe Piezometer is a reliable and cost-effective Casagrande type piezometer designed for monitoring in vertical boreholes. At Monitel, we have used it to measure groundwater levels and pore water pressures on sites across Western Australia.
The sensor is typically installed with the filter tip positioned at the chosen monitoring depth. For pressure data, the tip is surrounded by sand and enclosed with a bentonite seal to isolate the measurement area. Water level data can be gathered through a riser pipe or a Bourdon gauge (in artesian conditions). The W1 is suitable for various ground types and can be customised to match specific site requirements. It can be deployed with either a porous or ceramic tip and has a drive-in capacity for softer soils. The simplicity, versatility and reliability of the W1 Standpipe Piezometer make it an ideal choice for an accurate and consistent groundwater monitoring solution. Key Specifications:
The 4-20mA Piezometer is engineered to precisely measure pore water pressure in fully or partially saturated soil and rock. It is one of the more commonly deployed sensors in our piezometer range.
It utilises a diaphragm-type pressure transducer, delivering a robust 4-20mA output signal that is ideal for integration with data loggers and remote monitoring systems. It boasts an advanced and durable design, with 316-grade stainless steel and hermetic sealing protecting the technology from environmental effects. The casing itself is constructed to ensure that any stresses have no impact on readings. The 4-20mA is capable of measuring pressures from -50 kPa to 3500 kPa, accommodating a wide range of monitoring needs. Key specifications:
The W16 Kompakt Piezometer is a vibrating wire piezometer designed for fast and accurate measurement of pore water pressures.
It utilises proven vibrating wire technology, where changes in wire tension correlate to changes in pore water pressure. Data is then sent to a read-out, terminal unit or data logger. The W16 boasts a compact design, making it ideal for confined installations. It is only 19mm in diameter and weighs just 150g (excluding the filter and cable). However, it is also robust and durable, with hermetic sealing promoting resistance to environmental factors. An over-voltage surge arrestor safeguards against electrical damage. The sensor tip includes an integral porous element, which houses the vibrating wire technology. Key Specifications:
The VWP-3000 Series Vibrating Wire Piezometers are designed to provide measurements of pore water pressure across geotechnical and structural engineering applications.
These piezometers work by converting fluid pressures (exerted on a sensitive diaphragm) into a frequency signal. They collect reliable and accurate data suitable for monitoring groundwater elevations, pore pressures and fluid pressures.The series is built to withstand tough and demanding conditions, ideal for direct burial in fills, embankments and boreholes. Each model includes an internal thermistor and a 90V gas plasma arrester, acting as a safeguard against lightning strikes.
The VWP-3000 Series also features:
